Purple saxifrage Facts
Purple saxifrage is flowering plant that belongs to the saxifrage family. It can be found in the area of Arctic Circle, in Alaska, Rocky Mountains, Alps, northern Britain and northern Greenland. Purple saxifrage inhabits gravely and rocky areas and stream banks. It grows on calciferous soils, on the rocks and cliffs. Experiment designed to examine effect of increased temperature on the growth of purple saxifrage in the wild showed that this plant would not be able to compete with other plants after colonization of the "warmed" Arctic. That's why climate changes represent the major threat for the survival of purple saxifrage in the wild.
Interesting Purple saxifrage Facts:
Purple saxifrage grows in the form of cushion (dense mat) on the ground. It has short stem that can reach 0.8 to 2 inches in height.

Inuit use blooming period of purple saxifrage as a reminder of calving in caribou herds.
Purple saxifrage is one of the seven species that is monitored in the international scientific study (International Tundra Experiment) which examines effect of climate changes on the growth and reproduction of arctic plants.
Purple saxifrage is covered with flecks of calcium carbonate in the lime rich areas. These flecks provide protection against solar radiation and wind.
Purple saxifrage is territorial flower of Nunavut (Canada), Nordland county (Norway) and county flower of County Londonderry (Northern Ireland).
